Dissolved carbon dioxide concentration controls baseline stable carbon isotope signatures of a lake food web
Dissolved carbon dioxide concentration controls baseline stable carbon isotope signatures a lake food web
2014/4/4
Temporal variation in the baseline stable carbon isotope (δ13C) value of a well-studied, productive lake was examined over a 26-yr period using archived samples of the herbivorous zooplankter Daphnia ...

Carbon isotope composition of fatty acids and sterols in the scleractinian coral Turbinaria reniformis: Effect of light and feeding
Carbon isotope composition fatty acids sterols the scleractinian coral Turbinaria reniformis: Effect of light and feeding
2014/4/17
The effect of auto- and heterotrophy on the carbon isotope composition (d13C) of fatty acids (FA) and sterols was studied in the scleractinian coralTurbinaria reniformis. Colonies were maintained in a...

We examined the carbon sources used by bacteria and mesozooplankton in the Scheldt River and estuary
(Belgium, The Netherlands) using a combined stable isotope and fatty acid composition approach. Wa...
Patterns and controls of lotic algal stable carbon isotope ratios
Patterns and controls lotic algal stable carbon isotope ratios
2014/5/14
Spatial and temporal variations in stable carbon isotope ratios (i.e., δ13C) of primary producers are common but poorly understood features of isotopic characterizations of aquatic food webs. I invest...
A carbon isotope method to quantify groundwater discharge at the land-sea interface

We present a new method to characterize and quantify groundwater discharge to estuaries and the coastal ocean. Using data from the Pages Creek estuary in the Cape Fear region of southeastern North Car...
Light-dependent carbon isotope fractionation in the coccolithophorid Emiliania huxleyi
Light-dependent carbon isotope fractionation coccolithophore Emiliania huxleyi
2014/5/26
The carbon isotopic composition of marine phytoplankton varies significantly with growth conditions. Aqueous CO2 concentration [CO2] and algal growth rate (μ) have been suggested to be important facto...
